Review Summary

I am approving your solution because your tests thoroughly exercise getCoinCombination and satisfy all of the required checklist items. You correctly verify the specified example inputs (1, 6, 17, 50) with their expected outputs, ensuring the minimal coin combinations and the correct mapping of pennies, nickels, dimes, and quarters in the returned array. The tests use Jest’s describe, it, and expect(...).toEqual(...) consistently, and all inputs are non‑negative integers as required. It’s also good that you did not modify getCoinCombination.js, keeping the implementation file unchanged and focusing only on tests. Your additional cases (like 0, single-coin values, and larger amounts) strengthen confidence in the greedy coin logic and improve overall coverage. If you want to refine further, you could optionally organize tests into multiple describe blocks by input category, but this is not necessary for correctness. Overall, your work meets the task requirements and demonstrates solid testing practices—well done.
